Privacy
Online models see only what you choose to send. You sign in with your Flowsta Identity - created by you, kept in your own Flowsta Vault, 24 words as the key - so there is no provider account behind your requests: they reach the provider with no identity attached. Your Own AI keeps your conversation history, memory, and documents on your device, and attachments only go online with your explicit consent - the app asks. License: MIT (open weights, served via API) (terms).
